Don't create anonymous namespace separately, use the first namespace that is created for app classloader as the anonymous namespace. Note that the anonymous namespace is set via the new ANDROID_NAMESPACE_TYPE_ALSO_USED_AS_ANONYMOUS. I didn't creat a new function like android_set_anonymous_namespace as it requires uprev of the libnativebridge interface and makes it harder to delete the old android_init_anonymous_namespace as we have to keep it until all proprietary bridged loaders are updated.
